Copernicus.
The heliocentric model of the universe was first proposed by the ancient Greek philosopher and astronomer Aristarchus of Samos in the 3rd century BC, but it was Nicolaus Copernicus who revived and developed this idea in the 16th century. Copernicus published his groundbreaking work, "De revolutionibus orbium coelestium," in 1543, which detailed the model where the Earth and other planets revolve around the Sun, challenging the long-held geocentric view. This shift laid the foundation for modern astronomy and significantly influenced subsequent scientists.
Ptolemy was the first person to introduce the theory of a geocentric universe, a universe in which everything revolves around the earth itself. But in 1543, Nicolas Copernicus was the first person to introduce and prove the idea that the universe is heliocentric, a universe in which everything revolves around the sun.
The first person to promote the idea of the Heliocentric theory was Philolaus, a Pythagorean philosopher. The first "scientist" was Nicolaus Copernicus. He used his teacher's, Tycho Brahe precise measurements to help formulate how the stars moved in the sky and found that the sun moved much faster relative to everything else. He then explained away the movement by applying the Sun as the center of our solar system.
Aristotle did not believe that the Sun was at the center; he thought Earth was. Aristarchus, a Greek astronomer, is probably the earliest person we know of who supported a heliocentric solar system.

Copernicus
Nicolaus Copernicus was the first astronomer to formulate a scientifically-based heliocentric cosmology that displaced the Earth from the center of the universe. So yes I guess you can say he was a scientist.
Aristarchus of Samos was the first person (that we know of!) that proposed a heliocentric model of the universe, as early as about 200B.C). His model was rejected mainly because of Aristotle's influence.Copernicus was the next person to propose a heliocentric model of the universe which was published in 1547. although very controversial at that time, this model was the one that caught on.
While many say it was capernicus I think it was actually " Aristarchus" a couple hundred years before Capernicus.
Aristarchus
They were the first 'modern' (well, medieval) scientists to come up with the "heliocentric" view of the universe: the concept that the Earth revolves around the Sun and is not the center of the Universe itself. It should be mentioned that ancient Greek scientist had already discovered that some 1,500 years earlier, but their writings had been more or less forgotten by then. Well, not quite: it was much later discovered that Copernicus referred specifically to those earlier Greek findings in the draft of his book, but left it out in the final text.

Pythagoras was the Greek philosopher and scientist who conducted the first experiments in acoustics.

The first person to theorize a heliocentric solar system was Aristarchus, a greek philosopher. However, he was ridiculed, and the first person to have the idea accepted was Copernicus.
In the 16th century, Nicolaus Copernicus was the first to suggest the heliocentric model. His thought on the matter was that the sun was in the centre of universe, and that the earth, along with the other planets, rotated around it.
